.xMPRovEMENT 1N HrD'EMILLa The Schedule referred to in these Letters Patent and making part of the same.

We, JOHN P. FRIEND, of Peabody, in the county yof Essex, and Stateo'f Massachusetts, and `BlfiNulMIN R. ANNABLE, of Salem, in said county and State, have invented certaiulmprovements in Hide-Mills, of which the following is a specification. l

Our invention relates to the method of connecting the pitman, which actuantes thc beater of the mill, with the vibrating arm upon which thebeater is hung, (below'the beater',)in such a manner that the connection is made more perfectly than heretofore, andthe parts may be tightened or adjusted from the top of the beater with less diiiculty and trouble than is the case with the present method of adjusting the parts; and

. It consists, for this purpose,.in making the connection of the pitman and vibrating armby means of a strap, which-passes through oraround the .vibrating arm, having a bearing for theend of the pitinan ou one side, and a gib and key on the other side, the key .passing up through the beater, and adjusted by means ofa nut on the top ofv the beater;` and in carying Aan oil-tube from the working partsnp through the beater, so that the connections may be lubricated. v

Our invention is designed to overcome the dicultiesand imperfections ot the present method of adn justing the parts before described in hide-mills. As at present constructed and operated, itis very diicult to get at the connections furthe purpose of taking up the wear whichis the result of the continual jar and.'

vibration.

It has been found from` experience that it is essential to make this connection below the beater, and consequently, below the hidebox,and from this cause, whenever the connection wears 1oose,there are' no adequate-means for readily `adjusting it, and no 'method of lubricating'thetwearing parts. The wearV is thus .much greater, and there is more danger of injury to the mill from this cause. l 4- All the filth from the ,hide which is lbeing mille passes down into the cavity below the hide-box, where these connections are located, making it. a very disagreeable process to keep the connections iu order, or

to get at it for lubrication.

Our method of making these connections avoids all these difficulties bymaking the parts adjustable and capable of being lubricated from the top ofthe beater, and the result is that the mill operates mo1'e"`perfectly,

with less wear and injury to the moving parts, and with greater economy.

The drawing represents a vertical section ofthe beater, the lower part of the vibrating arm, and the parts employed in our new method of making the connection.

A represents the vibrating arm.

B is the beater, which is attached to the vibrating arm in-any suitable manner.

Q is a key, which' passes througha slot in the strap D, up through the beater to the top, where it is adjusted by a nut. The lower part of the key Gis wedgeshaped, to correspondwith the shape of the gib H.

The strap D is made of iron, or other suitable material, and passes through the vibrating arm. -It has a bearing, E E, onthe side opposite thekey C, for the -purpose ofholding the end of the pitman F. This bearing is made wider than the strap D,'for the purpose ofA shouldering against the side of the vibrating arm.

G isan oil-tube, which passes down through the beater B, through the strap D, and into the bearing E.

When the pitman F becomes loose from wear or other causes, it is only necessary to tighten the nut on the top of the beater, which raises the key C, drawing the strap through the vibrating arm, and tightening the bearing E, which incloses the end of the pit-mau.

We claim as our invention- 1. Connecting the pitman and vibrating arm of a.

3. The tube G,`passing down from the upper side ofthe beater to the bearing E E, for the purpose set l forth.
